To all whom it may concern:

Be it known that I, 'JosnPH D. Crrii, a citizen of the United States ofAmerica, residing at Dayton, in the county of Montgomcry and --State ofOhio, have invented new anduseful Improvements in Axle Bearings,

of which the following is a specification.

This invention relates to certain improvements in bearings for the axlesof trucks or cars. More particularly the bearings are designed for usein connection with cars used for transporting V brick in brick-makingplants. In such places the car tracks are more or less imperfect intheir laying, there being more or less variation in the elevation of therails and, therefore, it is desirable that the bearings for the axles ofsuch cars shall be free to compensate or vary in accordance with theamount of deflection that is imparted to the axles of the car due tosuch unevenness or lack of uniformity in track elevation and plane. Thepresent invention has for its object to provide an axle bearing for carsof this character which has both a maximum of anti-friction and afacility for oscillating .in lanes both parallel and transverse and inact any plane between planes that are ar'allel and transverse to theline of the ax e of the car. In other words, the

axle bearing is of the ball and socket or universal bearingtype with anelimination of a certain amount of the contacting surface between thetwo members whereby friction at some points is avoided, and the parts ofthe bearing may be easily disassembled and put together. The inventionconsists of the parts and their combination and construction as willhereinafter appear from the description and the claims to follow and 40in connection with the accompanying drawn. the accompanying drawingswhich form part of the description to follow and upon which likereference characters indi 5 cate similar parts as they are illustratedin the drawings.

Fig. 2 is an inner side elevation of the bearing intact, detached fromthe truck or car frame.

Serial No. 579,047.

Fig. 4 isa bottom plan view of one of the bearings intact with'the axlebroken awayto facilitate space.

Fig. 5 is asectional View on the line 5-5 of Fig. 3.

Fig. 6 is a sectional view on the line 66 of Fig. 2.

Fig. 7 is an end view of the ball or inner bearing member.

As hereinbefore stated, the invention is designed to afford the greatestrange of oscillation of the bearing around the end of the shaft or axlewhich is received therein. This is important for the reasonshereinbeforestated; due to the imperfect alinement of the rails forming the trackover which the car is moved and which are usually light. These cars, asbefore intimated, are used for transporting clay products in theirmaking, such as bricks, tile, etc, for example in transporting theproduct in the green state to the kilns for drying the same.

Having these ends in view the particular description of the bearing isas follows:

'1 designates a bracket which is rigidly attached to the truck or carframe 2. This bracket is strengthened or'reinforced by a longitudinalrib 3 which is a well known ex? pedient in the molders' art. The lowerportion thereof terminates in a shell or housing which constitutes theouter member of the bearing. This shell or housing 4 is of sphericalform which spherical form 'extends from the upper portion thereof intothe sides thereof. The top and sides form a rounded interior contactingsurface which incloses the ball or inner member 5 of the bearing. Thelower portion of the shell or housing 4 is omitted or removed so thatthe bottom thereof is open as at 6, and it is apparent that the weightof the car will keep contact between the bracket 4 and member 5.- Asshown inFig. 4. the ball member 5 of the bearing is exposed through theopen bottom of the shell, the upper portion thereof being in contactwith the upper rounded portion of the said housing, as is clearly theaxle 7; both in perpendicular and transverse planes as well as any planebetween these two planes of oscillation. Therefore,

it follows that a. maximum of compensation-is provided in the bearingfor all inequalities or irregularities of the track. The

axle 7 has a direct bearing in a series of roller bearings 8 which areassembled on the interior of the ball member of the bearing and these,together with the elimination of the lower portion of the housing 4;,provide a-minimum of frictional resistance at all degreesof oscillationwhich the axle may demand in passing over the car track.

.The opening 9 in the housing through which the axle projects in findingits bearlngis amply large to enable the greatest amount of oscillationof the ball 5. The wall 10 acts as a thrustbearing for the axle. The.car tracks in brick kilns are usually not laid by expert trackmen. Theconditions are such that it would be impossible to lay such trackperfectly owing to the lack. of a proper road. bed and other causes wellknown to: the brick-making art. Therefore, not only is there1found.lnequalities in the track due to higher and lower elevation of parts,butv often side deflections are present in these tracks and it is thesevarious irreguinner bearing member ofspherical form within saidhousing,the lower sideof said ing or socket member the interior top and theinteriorperipheral top wall thereof beserving as a thrust bearing forthe end of the axle and aninner bearing member havmg a form .to fitwithin said housing, wherehousing.

inner bearingmember beinguninclosed at a the "bottom of the housingwhereby it is subject to a universal movement within the housing with asubstantial curtailment of frictional engagement with said housing.

2. The combination with a car axle, of a bearing therefor consisting ofan outer housside walls thereof being; of a continuous spherial form andthe bottom thereof being open throughout its width, a ball constitutingan'inner bearing member within said housing and adapted to haveuniversal range of movement therein, the lower side of said ball orinner member being exposed through the opening. in thehousing andsaidinner memberhaving a series of roller bearings arranged thereinwhich receive the car axle.

3, The combination with a car-axle, .of a bearing therefor consisting ofa. housing ing in the form; of a frustum of a sphere and one ofthe sidewalls of the housing by it is" subject to a universal. movement withinthe housing ;witha.sub stantial curtailment of frictional engagementwith said 4. The combination with a car axle, of a bearing thereforconsistingbffan outer in. tegral housing or socket member the interiortop wall thereof" being in the form of a frustum of a sphere and a sidewall of the housing serving as a thrust bearing forthe end of the axle,a ball constituting an in: ner bear ng member within 1 said housingandadapted to have a universal range of movement therein', and' saidinner member havlng-a series of roller bearings arranged thereinjwhichreceive the caraxle.
